DIORIO CHRIS PH.D. 4

What Happened

• Chris DiOrio, Ph.D., CEO of Impinj (PI), had RSUs vest on 2026-06-23. A total of 3,040 shares were issued on conversion of RSUs (1,223 and 1,817 from two prior grants). To satisfy tax withholding obligations, 1,197 of those shares were remitted to the company at an implied withholding value of $125.22 per share, totaling $149,888. This was a routine vesting and tax-withholding transaction, not an open-market sale.

Context

• This was a vesting event and share-withholding to cover taxes (a cashless/withholding process), not an open-market sale—routine for RSU vesting and commonly seen in executive compensation filings.
• Transaction code M indicates conversion/exercise of a derivative (here, RSUs converting to shares); code F indicates shares used for tax withholding. These actions are administrative and do not necessarily signal insider sentiment.
